Purpose:Lower urinary tract symptoms (LUTS) can be caused by abnormal detrusor activity, bladder outlet obstruction (BOO), or numerous other factors. These factors must be evaluated with scrutiny, especially when prostate volume is small and the patient is about to have invasive treatment. We evaluated the urodynamic findings of patients with LUTS and small prostate volumes.
Materials and Methods :From January 2006 to December 2008, a total of 140 men with LUTS underwent urodynamic study. Of these 140 men, 51 patients with prostate volume ≤30 ml and an International Prostate Symptom Score (IPSS) ≥8 were evaluated.
Results:The average age of the patients was 65.5±7.4 years (range 46∼86), mean prostate volume was 24.5±5.1 (range 13.0∼30.0), mean IPSS was 15.5±7.7 (range 8∼34), and quality of life (QOL) score was 3.4±1.5 (range 3∼6). BOO was the most common finding, affecting 21 (41.2%) patients. The patients with BOO were significantly older than the unobstructed patients (70.1±5.9 and 62.4±6.7 years, respectively; p＜0.001) and had larger prostates (27.5±3.1 and 22.4±5.1, respectively; p＜0.001). Furthermore, they had higher IPSS, but the difference was not significant (p=0.074). Eighteen (35.5%) patients had normal findings, while detrusor underactivity (DU) was found in 15 (29.4%) and detrusor overactivity (DO) in 3 (5.9%) patients. There was no significant difference in age, prostate volume, or IPSS between men with and without DU.
Conclusions:The most common finding of LUTS with small prostate volume is BOO, even though it accounts for less than half of the patients. However, patients with normal finding or DU on urodynamic study account for majority of cases, emphasizing the value of urodynamic study before invasive treatments.
